HQ'SULATOR -SUP.PORT.

Specification of Letters Patent. Patented June 11,

Application filed January 3, 1918. Serial No. 210,138.

To all whom it may concern:

Be it'known that I, LEM E. Hnnnnn, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Insulator-Supports, of which the following is a description, reference being had to the accompanyin drawings, which are a part of this speci cation.

The invention relates to supports for-insulators.

In running lines for electrical transmission for difi'erent kinds of work it has formerly been the practice to use bracketshaving integral arms to which the insulators are secured. The difiiculty brackets is that special brackets have to be obtained for supporting two, three or more insulators and no provlsion is made to provide the same bracket for different arrangements of insulators. To obviate the disadvanta es of these former constructions it is the o ject of this invention .to provide a standard bracket with simple spacing members and fastening means whereby any desired numbers of insulators as used in practice may be mounted on the bracket and in any desired arrangement so that the insulator support may be furnished'as a standard unit to support different systems of wlrmg.

The invention is furthendesigned to provide an insulator support differing specifically in construction rom that shown and described in my co-pending application Serial No. 169,558 filed May 18, 1917.

The invention is further designed to provide a U-shaped bracket having a fastening screw rigidly connected thereto and an insulator supporting rod removably secured to the arms of said bracket, the bracket being readily put in lace by screwing its fastening screw into t e side of a building or other support. I

A further object of the invention is to provide a double U-shaped bracket that is, a U-shaped bracket within a U-shaped bracket and means for detachably securing them together so that the bracket maybe used for either two wire or three wire service, the arrangement producing astrong construction. v

The invention further consists in the several features hereinafter set forth.

In the drawings: Figure 1 is a view of the.device embodylng with these one piecethe invention showing one form of bracket, parts of one of the insulators being brokenaway; r 7

Fig. 2 is a similar view showing a larger bracket;

Fig. 3 is a view showing a modified form of bracket;

Fig. 4 is a central through the device.

In Figs. 1, 2 and 4, the bracket consists of a U-shaped member 5 provided with a fas-' tening screw 6 which is rigidly secured to the transverse portion of the member 5 by riveting the end of the screw therein though the bracket could be cast around the head of the screw or otherwise suitably rigidly se: cured. A member or rod 7 is removably mounted in the arms of the bracket and is provided with a'plurality of spaced apart holes 8 for receiving cotter pins 9 or pieces of bent wire 10. .These holes 8 are spaced substantially the length of an insulator apart though they may be farther apart, as in Fig. 1, to accommodate the interposed arms.

The rods 7 aredesigned to' removabl receive the usual spool insulators 11, said inhorizontal sectional view sulators being secured on the rod 7 between adjacent ins 9 and being spaced from each other if esired by said pins.

. In'Fig. 1 the size of the bracket is .such as to accommodate a single insulator between the arms and this'type of bracket may be employed for a single insulator using a'short rod though by using-a longer rod sothat portions project from the sides of the arms I am able to use one, two or three insulators.

In Fig. 2 the spread ,of the arms of the bracket is such as sulators therebetween and in this instance also the rod may be extended beyond the sides of the arms, as in Fig. 1, to accommodate other insulators variety of arrangements.

The brackets are readily fastened into .place by simply screwing the screw fastening 6 into a suitable support.

In Fig. 3 I have shown a strong construction which is very useful in practice. This' consists of a U-shaped bracket 5 similar to that of Fig. 2 having a similar rod 7 which the insulators are mounted and this rod may be extendedbeyond the sides of the arms, as in Fig. 1 to accommodate other insulators and. where a two wire circuit isused such an arrangement is preferred and in that case the bracket may be fastened to its to accommodate three inor secure a greater upon support by screws or bolts (not shown) pass-v ing through holes 12. When a three Wire circuit is desired the bracket of Fig. 1 is passed through an opening in the raised pori of the rod on the outside of the larger bracket and place. the third insulator on the rod between the arms of the smaller bracket. With this construction both parts may be sent to the user and he may put up the larger bracket for two wire service and then if at any future date the party wants a three wire service the rod 7 is removed and the smaller I bracket attached to the larger one, the rod replaced, and the insulators arranged as just described.

Of course it will be understood that the screw'6 of the smaller bracket shown in Fig. 3 may be out 01f flush with the outer face of the nut 14 in which case the screws passing through the holes 12 would secure the bracket in lace or the bracket of Fig. 1 may be attache to the larger bracket without the nut 14 by passing its screw 6 through the central aperture in the larger bracket and screwing it directly into the support.

What I claim as my invention. is:

1. An insulator support comprising a U- shaped bracket, a second U-shaped bracket disposed within the first bracket and de-' tachably secured thereto, the arms of said brackets being disposed in spaced relation to each other, a rod removably mounted in the arms of said brackets, and insulators removably mounted on said rod.

2. An insulator support comprising a U- shaped bracket havin an opening therein, a second U-shaped bracket disposed within the first bracket and having a threaded member passing through said opening and detachably secured to said first bracket, the arms of said brackets being disposed in spaced relation to each other, a rod removably mounted in the arms of said brackets, and insulators removably mounted on said rod.

In testimony whereof, I afiix my signa,

ture.
